SPECIFICATION forming part of LettersiPatent N 0. 548,314, dated October22, 1895.

Application tiled September 15, 1891. Serial No. 405,745. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM M. HOERLE, a resident of Allegheny, in thecounty of Allegheny and State of Pennsylvania, have invented a new anduseful Improvement in Lamps; and I do hereby declare the following to bea full, clear, and exact description thereof.

My invention relates to lamps, and more down to the lower outletthereof, the result being that the table or support for the lamp willreceive all such drippings.

The object of my invention is to improve the construction of the lamp inthis and other respects, as willmore fully hereinafter appear. I

To these ends my invention consists, generally stated, in a lamp havingthe upper edge of its wick-tube provided with an internally anddownwardly projecting lip and a tube within said wick-tube whereby anydrippings will fall from the wick over said internally and downwardlyprojecting lip to the space between said tubes, thus providing-a way ofescape for such drippings back into the fount of the lamp.

It further consists in certain other improvements and combinations ofparts, all of which will be more fully hereinafter set forth andclaimed.

To enable others skilled in the art to make and use my invention, I willdescribe the same more fully, referring to the accompanying drawings, inwhich- Figure l is a central sectional view showing my invention. Fig. 2is an enlarged detail View. Fig. 3 is an enlarged View of theflamespreader; and Fig. 4 is an enlarged view of the perforatedtruncated cone.

The lamp a consists of the fountor bowl I), having the centraldraft-tube csecured therein, the bottom of said fount being suppliedwith suitable air-entrances for the passage of central draft-tube 0consists of the two portions 0' 0 the lower portion extending up to theshoulder 0 where the diameter ofsaid draft-tube diminishes to form theupper portion 0 of smaller diameter than the lower portion 0'. Thewick-tube d surrounds the upper portion 0 of the central draft-tube cand is secured to the draft-tube c at the shoulder 0 The wick d fitsaround the lower portion 0 of the tube 0 and around the wicktube d, andis adapted to be raised or lowered thereon by anysuitable form ofmechanism. A collar 6 surrounds the wick d at the upper end thereof andserves as a guide for said wick. The upper inner edge of the wick-tube dis formed with the inwardly and downwardly projecting lip f. Thisinwardly and downwardly projecting lip fforms a kind of.

beading around the interior of the tube (Z, upon which any drippingsfrom the wick will collect in the form of globules. The lip f permitsthese globules to fall down between the inner surface of the wick-tube dand the outer surface of the contracted portion 0 of the tube 0. By theemployment of this lip f the inner surface of the tube (1 is kept freefrom oil, and the disagreeable odor arising therefrom is obviated. Belowsaid internallyprojecting lip f in the walls of the wick-tube cl areformed the openings g, arranged in any suitable manner at intervalsaround said tube. The upper portion 0 of the central draft-tube c is ofsuch a diameter at its upper end that when the wick-tube d is in placethere is sufficient space between it and the wick-tube d to allow anydrippings escaping over the edge of said wick-tube d to pass downbetween the said wick-tube d and the upper portion c of the draft-tubeo. The lower portion 0' of the tube 0 being of larger diameter, and asthe lower end of the wick-tube d is secured to the outer face of thedraft-tube c at the shoulder 0 a close connection is made between thetubes, so that any drippings falling down between the wick-tube d andthe upper portion 0 of the draft-tube 0 will be prevented from anyfarther downward progress. The opening g in the walls of the wick-tube dpermit of the escape of any such drippings, which will accordingly beagain absorbed by the air up through the central tube 0. This the wickd, thus preventing all liability of any of the oil escaping down throughthe tube 0 to the opening at the bottom thereof and thence to the tablesupporting the lamp. The openings 9 in the wick-tube d perform severalimportant functions. They permit of the escape of any gas generated inthe fount, while they also serve to cool the interior of the lamp as theheat-flow is broken by the perforations.

The flame-spreader 'i is provided with the annular groove or depressionj at such a point thereon that when said flame-spreader is in positionsaid groove will come opposite the internally-projecting lip f of thewick-tube d, thus permitting any oil escaping from the wick to pass overthe edge of the wick-tube (1, while at the same time it permits the airto pass between the flame-spreader 11 and the wick-tube d.

To obtain a thick steady flame, the flamespreader 'i has seen redtherein the perforated truncated cone is, which serves to check the rushof air upwardly in the spreader. This perforated cone is is situatedbelow the top of the wick-tube (1, so that the air is retarded below thepoint of combustion, and a more even steady flame is obtained,

I do not confine myself to the particular construction shown, as thecentral draft-tube 0 may have an equal diameter for its entire lengthand carry the wick d. A tube could be inserted within the centraldraft-tube to catch the drippings, the internally and downwardlyprojecting lip being formed on the upper inner edge of the draft-tube.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In alam p, the combination with thefount,

of a wick tube having on its upper and inneredge an internally anddownwardly projects ing lip, and a tube within said wick tube adapted toreceive any drippings from said lip of the wick tube, said two tubesbeing secured together so as to form a receiving trough, substantiallyas set forth.

2. In a lamp, the combination with the fount, of a wick tube having onits upper and inner edge an internally and downwardly projecting lip,and a tube within said wick tube adapted to receive any drippings fromsaid lip of the wick tube, said two tubes being secured together so asto form a receiving trough, and said wick tube having perforationstherein above the point of union of the tubes, substantially as setforth.

3. In alamp, the combination with the fount,

of a wick-tube having formed integral therewith on its upper and inneredge an internally and downwardly projecting lip, and a tube within saidwick tube adapted to receive any drippings from the wick tube, saidtubes being secured together, and said wick tube having perforations inthe wallsthereof above the point of union of the tubes, substantially asset forth. 4. In alamp, the combination with the fount, of a wick tubehaving on its upper edge an internally and downwardly projecting lip, atube within the wick tube adapted to receive any drippings from the wicktube, and a flame spreader supported on said inner tube, and having theupper part thereof perforated, and having an annular depression in linewith the inwardly and downwardly projecting lip of the wick tube so asto give space therefor, substantially as set forth.

In testimony whereof I, the said WILLIAM M. HOERLE, have hereunto set myhand.
